Analysis of retinal and cortical components of Retinex algorithms
Author(s): Jihyun Yeonan-Kim; Marcelo Bertalmío

Paper Abstract

Following Land and McCann’s first proposal of the Retinex theory, numerous Retinex algorithms that differ considerably both algorithmically and functionally have been developed. We clarify the relationships among various Retinex families by associating their spatial processing structures to the neural organizations in the retina and the primary visual cortex in the brain. Some of the Retinex algorithms have a retina-like processing structure (Land’s designator idea and NASA Retinex), and some show a close connection with the cortical structures in the primary visual area of the brain (two-dimensional L&M Retinex). A third group of Retinexes (the variational Retinex) manifests an explicit algorithmic relation to Wilson–Cowan’s physiological model. We intend to overview these three groups of Retinexes with the frame of reference in the biological visual mechanisms.
